WATER STRAINE R OR SCREEN.

SPECIFICATION forming part Of Letters Patent No. 672,021, dated April16, 1901.

Application filed December 3, 1900. Serial No. 38,535. (No model.)

T0 at whom it may concern:

Be it known that I, CHARLES O. TAGGS, a citizen of the United States,residing at Ohicago, in the county of Cook, State of Illinois, haveinvented certain new and useful Improvements in Water Strainers orScreens, of which the following is a clear and exact description,reference being had to the accompanying drawings, which form a part ofthis specification.

My invention relates more particularly to screens used in filters forpreventing the filtering material, such as sand, from passing out withthe filtered water when in operation.

The object of my invention is to provide a screen simple in itsconstruction and more effectual in its operation and more durable thanscreens heretofore produced. I attain said object by the constructionshown in the accompanying drawings, in which Figure l is a sideelevation of my screen as it appears when complete. Fig. 2 is a verticaland central cross section showing the threaded end of the bottom part infull. Fig. 3 is a vertical and central longitudinal section showing thescrew or bolt which holds the screen together in full. Fig. 4: is a planview showing more clearly the two perforated openings formed in the topof the screen. Fig. 5 is a detail of the bottom part of the screen,showing an opening down through the threaded end of the same. Fig. 6 isa detail of the cylindrical part of my screen, showing the manner offorming the perforated openings therein. Fig. 7 is a reduced plan Viewof one of my screens attached to a piece of pipe and showing anotheropening produced in said piece of pipe to receive another screen in themanner used in filters.

In referring to the drawings like letters refer to like parts throughoutthe several views.

In the drawings, A represents the bottom part of my screen, beingprovided with the hole a down through the threaded end b, the squareshoulder c, the flaring sides d d, and the curved-out ends e e, asshownin Fig. 5.

B B are the heads or caps, provided with the lugs g g and a hole in thecenter of each of said caps to admit of a screw or bolt, as shown inFig. 3.

O is a cylindrical-shaped piece of metal of a suitable length anddiameter and being provided with four openings ffff, formed in itscircumference.

D. is a tubular-shaped piece of perforated metal of a suitable lengthand diameter, as shown in Fig. 6.

E is ,a cylindrical-shaped piece of metal of a suitable length anddiameter and being provided with four openings formed in itscircumference and corresponding with the openings ffff, formed in O.

F is a screw or bolt used to hold my screen together.

G is a piece of pipe with one of my screens attached and being providedwith the hole It to admit of attaching another screen.

In constructing my screen the parts shown in Fig. 6 being of same lengthand suitable diameter are forced together, the perforated metal beingbetween the inner and outer pieces, thereby forming the four perforatedopenings in the cylindrical part of my screen, as shown in section inFigs. 2 and 3. Said cylindrical part being of suitable length anddiameter is then placed in the curved-out ends 6 e and fits between theflaring sides (1 21, thereby forming a chamber in A, into which the twobottom perforated openings terminate, the other two of said perforatedopenings being on top, all as shown in section in Fig. 2. The caps'B Bare then placed over the ends of the cylindrical part, with the lugs g gat the bottom. The bolt F is then inserted. It will be readily seen thatas the bolt F is tightened the caps B B are drawn together and the lugsg 9 come in contact with the flaring ends of A, thereby securely boltingthe entire screen together, as shown in Figs. land 3.

" When in operation,one or more of my screens are attached to one ormore of theoutletpipes commonly used in filters in the manner nating inthe chamber formed in A and thence down through the opening a into theoutletpipes.

I do not confine myself to the identical construction shown, as in someinstances I dispense with the inner cylindrical-shaped piece E and insome instances with both the inner cylindrical-shaped piece E and theouter cylindrical-shaped piece 0, using only the tubular-shaped piece ofperforated metal D, being formed of a suitable diameter, therebyincreasing the filtering capacity of my screen without enlarging theother parts; nor do I con fine myself to the number of openings shownand described in O and E, as any nu mber may be used and of Variousshapes; but

What I do claim as new, and desire to secure by Letters Patent, is
